The point is, restaurants are about more than just food, and phones often serve to get in the way of the conversation and company that are integral to great restaurant experiences. That said, should you find yourself left to your own conversational devices while your tablemate blinks at their touchscreen, chuckling at whatever Miguel Bloombito just tweeted, don't be afraid to fight fire with fire -- send a warning shot by way of text. "I'm walking out if you don't put your phone away" should do it.
